BUTTON-FASTENING.

SPEGIFIGATION forming part of Letters Patent No. 248,278, dated October 18, 1881.

Application filed May 26, 1881. (No model.)

I all ughom it may concern:

Beit" known that I, BERTHOLD BLooK, of NewjYork, in the county and State of New York,"have invented an Improved Button-Fastening, of which the following is a specification.- Figure 1 is a central section of my improved button-fastening, showing it before it is completely secured tothe fabric. Fig. 2 is a side view of the button, partly in section, showing it completely attached to the fabric. Fig. 3 is a top view of the lower fastening-plate when the same has been bent flat. Fig. 4 is a contral section through the button on the line 0 c,

Fig. 1. Fig. 5 is a bottom view of the fastening when in the condition shown in Fig. 2. Fig. 6 is a central section through the lower plate, taken on the plane of the line k k, Fig. 3. Figs. 7 and 8 are perspective views of said bottom plate, showing a slightly-modified form of construction.

The object of this invention is to provide a button with means for rapidly and securely attaching itto a garment without requiring the necessity ot'sewingit orofstitchingofany kind; and the invention consists in combining the button proper, which has downwardly-projecting flexible prongs, with abottom plate that is first formed into a U shape and provided with channels for receiving said prongs, all arranged so that when, after the prongs are inserted into the channels of the bottom plate, the latter is bentflat,theprongs willalso behentandlocked, and the attachment thereby completed.

In the accompanying drawings, the letter A represents a suitable button having attached to its lower side two downwardly-projectiug prongs, ac, both made of thin brass or copper or similar material of the kind usually employed as paper-fasteners. These prongs are in suitable manner secured at their upper ends in the button A and extend downward from said button.

B is a plate, of circular or other form, made also of thin sheet metal or analogous material,

and provided at its upper face with two receptacles or channels, I) b, which stand in line when said plate is in a flat condition, as in Fig. 8, and are separated from each other by an intermediate blank space. These channels are for the reception of the prongs a a.

When the button is tobe attached the plate B is doubled up into U form,as shown in Fig. 1, so that the two channels or chambers b b are in a vertical position at the same distance apart, about, as the prongs a a. After the prongs have been passed through the cloth 0 they are inserted in these vertical channels, as in Fig. l, and thereupon the flexible plate B is bent flan-as in Fig. 2, thereby also bending the prongs at below the fabric 0 into a horizontal position and locking the button to the fabric and covering thenr from outer contact.

The plate B may either be of the form shown in Figs. 7 and 8 or as in Figs. 3 and 6-that is to say, the channels I) b may either be separately raised, as in Fig. 8,0r they may be formed through thicker lugsthat project from the upper face of the button, as in Fig. 3.

I'claim- The combination, with a button having depending attaching-prongs'a, of a flexible plate, B, provided with receiving channels or chamhers 1) upon its inner face, adapted to receive BERTHOLD BLOCK.
